Josh Rubenstein's Weather Forecast (Aug. 7)

STUDIO CITY (CBS) — Get ready for a prolonged heat event. There is no relief from the century readings for the rest of the week.

Many valley cities easily surpassed the century mark Monday and will continue to do so through Saturday. The high pressure responsible for the hot weather has parked itself in the southwest. There is nothing to kick it out right now.

The good news: it's a dry air mass, so we are not getting an excessive heat warning. That lack of moisture is also translating into a diminished thunderstorm chance; the monsoonal flow is being kept off to the east.

Aside from some cumulus build up, we are going to stay dry. However, by the end of the week, as the moisture drifts back into California, our humidity levels may increase and that may spawn an excessive heat advisory.

Beaches are staying nice with cooler than average water temps and a little marine layer.

Beaches - mid to upper 70s
Basin -upper 80s to near 90
Valleys - upper 90s to low 100s
Deserts - low 100s
Mountains - low 80s
